LIQUID-DISPENSER.

Specification of Letters Patent.

Patented Nev. a5, rara Application filed November 28, 1916. Serial No. 133,875.

To all whom z't may concern:

Be it known that I, FREDERICK M. FURBER, a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Liquid-Dispensers, of which the following description, in connection with the accompanying drawings, is a speciication, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to a liquid dispenser and particularly to a device for economically and neatly ,dispensing semi-viscous`liquids such as enamel, cement and the like.

Certain semi-viscous liquids deteriorate or .harden upon exposure to the atmosphere and A feature of the invention consists in a delivery trough mounted above the normal level of the liquid within the receptacle and arranged'to deliver liquid exteriorly of the receptacle together with a combined stirrer and conveyer which is preferably rotatable and is adapted to dip into the liquid to `stir the same and raise it above its normal level for delivery to the trough.

Important features of the invention are found in the mounting of the delivery trough above the normal level of the liquid in the receptacle and in its construction which is such as to provide for overflow of excess liquid into the receptacle whereby overflow of liquid at the delivery end of the trough is precluded.

Another feature of the invention consists in a finger cup which may be filled with a small quantity of the liquid to be dispensed and which is arranged so that an excess be returned to the receptacle. In a practical form of the invention, the means for supplying the cup with liquid from the receptacle is constructed andy arranged to maintain the liquid at a constant level in the cup below the brim thereof.

Other features of the invention will be apparent from a consideration of the fol'- lowing Specification together with the appended claims wherein the scope of the invention is delined.

In the accompanying drawings,-

Figure 1 is a front; elevation of the device; and

Fig. 2 is a view section.

A receptacle 10 is provided with ribs 12 arranged to support the neck of an inverted bottle 14 containing the liquid to be dispensed andhas a substantially air-tight cover 16 which may be retained in place by means of a thumb-screw 18. The lower part of the receptacle is so designed that its capacity to the top of the ribs 12 is substantially thesame as the capacity of the inverted bottle 14. It is found 'in practice that Awhere semi-viscous liquids of the nature indicated are used directly from the bottle, there is a considerable loss due to hardening on the bottle or inability to drain the contents completely within a reasonable in vertical transverse period. By means of this construction, howlfrom exposure to the air.

An extension 20, at one slde of the receptacle, is provided with a removable wall 22 at the center of which is arranged a hollow boss 24 adapted to act as a bearing for the hub 26 of a rotatable ring or hollow drum 28. A star lwheel 30 may be attached to the outer end of the hub 26 to enable the ring 28 to be rotated readily. This ring will preferably be so located that its center and in fact ay major portion of its periphery is above the normal level of the liquid in the receptacle, which level will never be above the top of the ribs 12. -Ou the other hand,

illustrated, this trough is arranged concen-l tricallyA with the rotatable ring and within the hollow hub 26. Itis secured against ro tation by means of a bracket 36 fastened at one end to the inner end pf the trough and at its other end to the removable wall 22 of the receptacle. By means of this arrangement, all moving parts of the device with the trough may be removed from the receptacle by detaching the wall 22. A flange 38 is provided upon the outer end of the trough to cover the end of the hub 26 and the hub of the star wheel '30 thereby avoiding the possibility that some of the liquid might vwork into the bearing of the rotatable hub 26. The trou-gh is preferably covered within the hub 26 to prevent contact of the liquid therewith and its inner end is cut away at 40 to\a point below the level of the walls of the trough outside of the receptacle so that it will overflow into the receptacle in case an excess supply is delivered thereto and tend to maintain the liquid in the linger cup 34 at the desiredA level. Above the inner end of the trough and co-acting with the inner periphery of the ring or hollow drum 28 is a scraper 42 which is formed integrally with the receptacle 10 and is adapted to remove the liquid picked up by the ring and transfer it to the trough. Obviously, the exact vertical relation of the scraper and trough illustrated, is not essential.-

When it is desired to use the device, supposing that a bottle of enamel o'r slmilar liquid has been inverted within the receptacle, the ring 28 will be rotated by means of the star wheel 30, thereby raising the liquid above its normal level to deliver it, with the assistance of the scraper 4-2, to the `outlet of the receptacle, here the trough 32. When the trough 3-2 hasbecome filled, the liquid will enter the lfinger cup 34: and it may be removed in small quantities for use.

\ Any excess of liquid in the trough will overflow the cut away portion 40 into` the receptacle, thus avoiding waste of the liquid by spilling outside of the receptacle. When the level ofliquid in the trough has been lowered by use s othat the liquid no longer enters the finger cup, it is only necessary to rotatethe ring by the star wheel 30. This will transfer more liquid to the outlet trough and at thesame time stir the contents of the receptacle to remix the constituent parts which may have been separated by standing for a considerable period.

Although I- have herein shown and de- I scribed the preferred embodiment of this invention, it is to be understood that various modifications thereof may be made without departing from its true scope and spirit as defined in the followingclaims.l

Having fully described my invention, what I claim as. new and desire to -secure by Letters Patent of the United States is 1.
